Question

11.
3 pens and 3 notebooks cost $13.50 while 4 pens and 14 notebooks costs $51.00.
let x and y be the prices of a pen and a notebook respectively.
(some options for x and y values, then)
11b is the solution viable in the given context?
options: yes (a), no (b)

Explanation:

To determine if the solution is viable, we check if the prices (x for pen, y for notebook) make sense in the context of buying pens and notebooks. Prices should be positive (since they represent costs) and reasonable for such items. If the solution gives positive values for x and y (e.g., from the previous part, likely valid prices), then the solution is viable as it satisfies the real - world context of non - negative costs for goods.

Answer:

A. Yes
